You can do a "manual" restore.
Go to your backup folder, and unzip one of the backup file in a temp folder.
If you're using the user folder ("Documents and Settings" or "Users") copy each .ics file inside every calendar folder into [USERFOLDER]/.rainlendar2, also copy in this same folder the .ini files. (this would be for a normal installation).
If you have several backups, check first if the calendars file had event stored and it's not an empty container.
Also, try restoring a previous backup and not the last one, because the last one is the one done in the last running. I mean, it's only 1 for day, and (maybe) you could changed it in the process.

Okay, I followed these directions. Still nothing. No events, no changes.

Took my files to a friend's house that is running Windows 7 and we installed Rainlendar 2.11 Pro and used my backup files via the Manager and it worked like a charm (we uninstalled after seeing it worked). But using the very same files on my Windows XP machine? Nothing. No events. Nothing.

I was thinking in another approach. Maybe it's the difference between XP and 7.
Before copy the rainlendar2.ini file, and keeping Rainlendar2 closed, open the file and search for "[iCalendar\ Format]". There you will find a list of the .ics files. If the path is stored in absolute way (full path) then the calendars won't be found. Replace "C:\\Users\\..." to "C:\\Documents and Settings\\...".
